  "textContent": "> I got it working and am responding to you from a Basilisk build that is using gtk2-ng right now. The performance is definitely closer to a GTK3 build. All I had to do is set LD_LIBRARY_PATH to the folder where I installed gtk2-ng and it just worked. I didn't modify the build system, it just linked against my system GTK2. So your goal of maintaining ABI compatibility definitely works.\n>\n> I ran into the issue that gtk2-ng did not include all of the GTK2 theme engines so my OS theme did not work. I'm not sure what the original GTK2 behavior was in this regard. I had to add the directory where my OS package manager has the GTK2 theme engines installed for my theme to the LD_LIBRARY_PATH as well for the theme to work. I did verify that it was still using gtk2-ng after that path to the LD_LIBRARY_PATH to verify that adding that directory didn't break gtk2-ng or cause the build to revert to system GTK2.\n\nThat's amazing! Thanks for testing! I'm going to make it even faster very soon\n\nRegarding the theming engines:\nI'm not at home right now, but this will be the next thing I'm going to take care of.\n\n\n> Hi there. Just for the sake of it I tried to build this Gtk2 project of yours. Apart from a few deprecations I got a warning about an implicit declaration, and then later on an error upon linking related to that declaration. Dunno how to fix this.\n> Running Linux Mint 19.2 (Ubuntu 18.04) with some backports, build tools GCC 9.5. Configuration log:\n>\n> Gtk2-NG_configuration_log.zip\n>\n> **EDIT:** Ah, it's probably due to **Glib 2.72.4** missing g_sort_array. It's only available starting with 2.82.  Can't install a newer glib unfortunately. Any workaround?\n>\n>\n> CODE:\n>\n>\n>     gtkfilesystemmodel.c: In function ‘gtk_file_system_model_sort’:gtkfilesystemmodel.c:804:7: warning: implicit declaration of function ‘g_sort_array’ [-Wimplicit-function-declaration] 804 | g_sort_array (get_node (model, 1), /* start at index 1; don't sort the editable row */ | ^~~~~~~~~~~~[...]./.libs/libgtk-x11-2.0.so: undefined reference to `g_sort_array'collect2: error: ld returned 1 exit statusmake[4]: *** [Makefile:2962: gtk-query-immodules-2.0] Error 1[...]./.libs/libgtk-x11-2.0.so: undefined reference to `g_sort_array'collect2: error: ld returned 1 exit statuslinking of temporary binary failed: Command '['/bin/bash', '../libtool', '--mode=link', '--tag=CC', 'gcc', '-o', '<project path>/Gtk2-NG/gtk/tmp-introspectfivxap7y/Gtk-2.0', '-export-dynamic', '-DG_DISABLE_SINGLE_INCLUDES', '-DATK_DISABLE_SINGLE_INCLUDES', '-DGDK_PIXBUF_DISABLE_SINGLE_INCLUDES', '-DGTK_DISABLE_SINGLE_INCLUDES', '-g', '-O2', '-Wall', '<project path>/Gtk2-NG/gtk/tmp-introspectfivxap7y/Gtk-2.0.o', '-L.', 'libgtk-x11-2.0.la', '-lgio-2.0', '-lgobject-2.0', '-Wl,--export-dynamic', '-lgmodule-2.0', '-pthread', '-lglib-2.0', '-lglib-2.0']' returned non-zero exit status 1.make[4]: *** [/usr/share/gobject-introspection-1.0/Makefile.introspection:156: Gtk-2.0.gir] Error 1\n\nHey there! Yeah, I didn't expect people to use thus fork on older systems, because gtk2 is still available on basically any distro from the last 5 years.\nThis should be an easy fix though.\n\n* * *",
